Wellll see I kinda ditched the entire Jedi!Sabine narrative. Listen if they HAD to go that direction, I believe they could have done it well but they really did not (to put it generously), and while I've considered trying to do it better myself, at the end of the day I wish they just hadn't done that at all.
Tldr: Ahsoka and Kanan probably will have a giant wolf to giant wolf conversation but idk if it'll be about looking out for Sabine or searching for Ezra or what
So this is my tentative and unrefined interpretation of Ahsoka and Sabine's relationship for SWW Ahsoka, aka roughly how I imagined it would be like before that damn show ever came out (sorry in advance this spiraled all over the place. I meant to elaborate a little bit and then I couldn't stop. I tried to keep it concise but. There's a lot to unpack that I didn't expect to have to unpack in order to get to the point lol)
First and foremost Sabine isn't fucking Force-sensitive. Ahsoka teaches her a lot about the Jedi, and continues her lightsaber training, and I think Jedi teachings and excercises can have a lot of value to ordinary people! But she's not trying to be a Jedi. Ahsoka does feel mentorly instincts towards Sabine, partly bc she knows what she's going through as a very young veteren and genocide survivor. Partly bc she does feel the need to pass her knowledge on to someone. Partly bc deep down Ahsoka is pretty damn lonely too, and Sabine is very family-shaped. And also because wolfwalkers stick together.
They call her Ahsoka's 'practice padawan' as a joke. Huyang is like. You really ought to find a Padawan one of these days. And Ahsoka's like. Why would I need a Padawan I have Sabine. And Huyang is like. Listen I'm very happy to have Sabine with us but you ought to get a real Padawan.
But how could Ahsoka ever take on a student while she's still wrangling with whether or not she wants to be a Jedi? Which, they never actually show her making a decision on that. Or rather there's really no transition between "I am no Jedi" and whatever she's got going on in the show which. Long story short, I hated it. Ass writing. In my personal opinion.
I think I’m just gonna lean into the idea that she feels like she can't truly be a Jedi whether she wants to or not bc she was trained to be a soldier instead, combined with the fear of Anakin's darkness manifesting in herself, distrust of his training, etc. Up until the point where she decides to put Anakin behind her for good and trust in her own experiences, during her WBW adventure (which goes way differently in my head but I will elaborate on that later. Maybe.) But for the purposes of this au, she doesn't even commit to being a Jedi again until dying for the 3rd(?) time and honestly maybe she still doesn't. Maybe it takes all the way to wet puppy Shin dropping in her lap that she sees her path as a Jedi path. Idk.
Ahsoka's arc is not an aspect of the story I expected to address in depth myself so idk how much I'm gonna get into it within the comic itself. It's hard to go over every issue bc lothwolfwalkers is just an anthology series adapting small chunks of the timeline that I find work well with the wolfwalking, and I'm trying not to make more work for myself than I have to, bc I already have plenty. Rewrite is maybe a strong word, when I'm just cherry picking what I liked from the ahsoka show and adjusting what I didn't like in a way that keeps the overall plot intact for simplicity sake. I will eventually write an official detailed ahsoka-from-my-head post, but the comics will just be little scenes based on that.
Regarding Sabine and Ahsoka's falling out. It doesn’t happen. In fact I think Ahsoka will take Sabine under her wing after the fall of Mandalore and they just immediately start looking for Ezra in the unknown regions, bc Sabine is like hey I have nothing left here can we go look for my brother now. They don't find anything. Eventually Ahsoka gets wrapped up in other business and Sabine ends up back on Lothal depressed as fuck (despite Kanan, Hera, and Zeb's best efforts to be there for her, infinitely more than what is depicted in the show) until Ahsoka finds the map and shows up for round 2. Or smth like that.
Side note: I am going to declare the Wrens MIA not dead. Because I hate hate hate that they were unceremoniously killed off screen and wasted the way they were. I guess I could just unkill them completely but well I am a sucker for that angst and something about the devastation of that reveal seared it so deep in my head that I can't imagine the story without it now (thanks for that Dave. Fuck you Dave.) So uh, they're trapped on Mandalore with those other survivors from Mando S3. After Sabine's already left for Peridea they manage to finally get off Mandalore due to S3 events and track down Hera and are like WHERE IS SABINE. Cue Clan Wren Ghost Crew team up to get their fucking kids back. Though everyone will probably make it back on their own before they figure out a way to hop galaxies.
